A DEVICE FOR MATERIAL REMOVING PROCESSING OF SUBSTANTIALLY VERTICAL MATERIAL LAYERS AND METHOD FOR RENOVATING DAMAGED, SUBSTANTIALLY VERTICAL, CONSTRUCTIONS

摘要

A device for material removing processing of substantially vertical material layers, especially on columns (6) and the like, comprises a carrier (1), a guide (2) arranged on the carrier, a carriage (3) movable to and fro along the guide and carrying a jet tube (4) for directing a high pressure fluid jet towards the material layer, at least a first driving means (7) for driving the carrier vertically so as to move the guide along the substantially vertical material layer, and at least a second driving means (8) for driving the carriage (3) along the guide.
